Listeners can recognize musical excerpts less than one second in duration (plinks). We investigated the roles of timbre and implicit absolute pitch for plink identification, and the time course associated with processing these cues, by measuring listeners’ recognition, response time, and recall of original, mistuned, reversed, and temporally shuffled plinks that were extracted from popular song recordings. We hypothesized that performance would be best for the original plinks because their acoustic contents were encoded in long-term memory, but that listeners would also be able to identify the manipulated plinks by extracting dynamic and average spectral content. In accordance with our hypotheses, participants responded most rapidly and accurately for the original plinks, although notably, were capable of recognition and recall across all conditions. Our observation of plink recall in the shuffled condition suggests that temporal orderliness is not necessary for plink perception and instead provides evidence for the role of average spectral content. We interpret our results to suggest that listeners process acoustic absolute pitch and timbre information to identify plinks and we explore the implications for local and global acoustic feature processing.

绝对音高和音色在 Plink 感知中的作用

听众可以识别持续时间少于一秒的音乐摘录（plinks）。我们通过测量听众的识别、响应时间和对从流行歌曲录音。我们假设原始 plink 的性能最好，因为它们的声学内容被编码在长期记忆中，但听众也能够通过提取动态和平均频谱内容来识别被操纵的 plink。根据我们的假设，参与者对原始 plinks 的反应最为迅速和准确，尽管值得注意的是，能够在所有条件下识别和回忆。我们在洗牌条件下对 plink 召回的观察表明，时间有序性对于 plink 感知不是必需的，而是为平均频谱内容的作用提供了证据。我们将我们的结果解释为建议听众处理声学绝对音高和音色信息以识别 plink，我们探索对局部和全局声学特征处理的影响。
